Extrusion International 2-2018

29 Extrusion International 2/2018 ing and material inlet. After shaping, the cooled article material and flash are very hard, requiring coordinated cut- ting mills. For an optimally coordinated, high-performance periphery, BEKUM brings with it the experience gained from many installed user projects and relies on tried and tested, high-perfor- mance partners. Practice-oriented automation to increase productivity Last but not least, automation plays an important role for the user if efficiency should be increased. Especially for con- tainers with an integrated handle, fully automatic and guided flash removal is important. Furthermore, the auto- mated removal with removal grippers and alignment by a turning station for placing on an article production line, increases efficiency of the operation. With its convincing performance char- acteristics and the system design opti- mally aligned to PC water bottle pro- duction, the BA series is a reference in water bottle production. BEKUMMaschinenfabrik GmbH Kitzingstr. 15/19, 12277 Berlin, Germany Clamping and plasticising unit impresses in production The quality of the BA 25 from BEKUM is apparent: The BA 25 machine is de- signed for discontinuous accumulator operation as well as bottom calibration and uses parison spreaders with verti- cal adjustment. Modern controls and hydraulics allow the processor very ac- curate repeatable cycles for high effi- ciency production. The BA 25 systemhas also excellent plastification. BEKUM ex- truders use a special screw geometry for optimum homogenisation of the mate- rial. An energy-saving ACmotor ensures that the material is melted gently at low rotational speeds. The patented spiral mandrel distributor head technology from BEKUM allows uniform wall thick- ness over 360° of the water bottle and offers reproducible product quality that is second to none. This in-house devel- opment by BEKUM practically excludes article thinning and flowmarks, ensures a crystal-clear water bottle transparency with a cloud-free surface and, by doing so, enables products of high quality. High efficiency at the forefront The highly transparent PC containers are blown out in a special blow mould, which has multi-zone temperature con- trol and magnetic quick-change inserts, with or without a handle. The BEKUM single-station blowers of the BA series achieve an undisputed output of over 160 containers / hour at a net weight of 750 g based on the reference article “Nestlé 5 Gallon Aqua Design without handle”. This high output rate is pos- sible without compromising the high ar- ticle stability as well as the crystal-clear transparency, even at demoulding tem- peratures of over 85°C. Sophisticated polycarbonate PC containers are country-specific and made out of pure new materials (e.g. from Bayer Makrolon, Mitsubishi No- varex and other PC materials), a vary- ing material mix of new material and recycled material, as well as 100% recy- clates. Processors know: When melting, polycarbonate is a sensitive material. This requires specially tailored mate- rial handling systems for material dry- To this day polycarbonate (PC) is the most used material in the manufactur- ing of water bottle containers over 10 litres. This is due to the excellent mate- rial properties for stability, cleaning and transparency. Thanks to the transpar- ency of the PC water bottle, with just a quick glance at the water level you can see when it is time to replace it. Replac- ing the water bottle is easy thanks to the practical cartridge system. The high- quality optics of the container also adds an appealing look to the water. The container size of 5 gallons (18.93 litres) is a widely used standard size with high quantities. It is designed in such a way that it fits all dispensers which are com- mon in the market. BA series with high market shares Extrusion blow moulding plants for BEKUM’s BA series have been firmly established in this market segment for years. The BA 25 by BEKUM is a very marketable PC water bottles machine that combines high performance and ef- ficiency. With a clamping force of 200kN and its compact footprint, the BA 25 is the obvious choice for manufacturing water containers. It has a very stable clamping unit and is highly wear-resis- tant. The BA 25 machine has been de- signed for high durability as well as long production capability and has long pro- vided a reliable and, above all, economic contribution to the drinking water sup- ply via water dispensers worldwide.
